- Implemented changes suggested in review by missytake:
- Removed relation between acmetool-redirector and certs.
- Added internal nginx listening on port 8443.
- Changed direction of arrows between certs and the services that
use them. This makes the arrow show the direction of
information flow, rather than a "depends on" relation.
- For filesystem paths, added a descriptive name to the node.
- Replaced most arrows with plain lines, to simply show that a
relationship exists between the two nodes. This also reduces visual
clutter, since the graph is pretty dense with information already.
- Split nginx and certs into two nodes, to reduce entanglement in the
graph. These "linked" nodes are given a different shape and filled
with a different colour, to highlight the fact that they are the
same node.
- Revised text about the meaning of edges in the graph.

The edges in this graph should not be taken too literally; they reflect some sort of communication path or dependency relationship between components of the chatmail server.
